Description

Technical Field

[0001] The utility model relates to the technical field of power sockets, in particular to a five-hole socket. Background Art

[0002] Power sockets are an indispensable electrical device in modern life and work. Sockets can be divided into three types according to the hole type: double-hole type, three-hole type and five-hole type. Among them, the five-hole type is also called a universal socket. Its biggest feature is that it can provide a two-pole socket and a three-pole socket on one socket, so it is widely used.

[0003] The base and panel of the existing five-hole socket are usually assembled by snap connection. For example, the utility model patent with patent application number CN201820168241.0 discloses a five-hole safety socket for manual protection door. The five-hole panel is provided with symmetrical snap holes on both sides, and the base of the five-hole socket is provided with two snaps. When assembling, the snaps are used in conjunction with the snap holes. The snap connection method has the advantages of simple connection structure and can be fixed without screw connection. However, the structure has a certain degree of difficulty in disassembly. Due to its tight fit, when one side of the five-hole panel is first opened outward to separate the snaps on this side from the snap holes, the other side of the five-hole panel is subjected to force, resulting in a tighter fit, making it difficult to open the other side. The force required to open both sides at the same time is greater, and tools are required. It is very laborious and easy to get injured by hand operation. Therefore, it is necessary to improve the structure. Utility Model Content

The five-hole panel 2 is provided with an outer two-hole socket 6 and an outer three-hole socket 7. A buckle arm 8 is provided on both sides of the five-hole panel 2. The buckle arm 8 and the five-hole panel 2 are an integrated structure. The two buckle arms 8 are symmetrically arranged. The buckle arms 8 are provided with buckle holes 9. A connecting buckle 10 matching the corresponding buckle hole 9 is provided on both sides of the base 1; the base 1 is also provided with a The quick-release structure 11 includes a plug 12, a guide groove 13 is provided on both sides of the base 1, the connection buckle 10 and the buckle arm 8 are arranged in the corresponding guide groove 13, the plug 12 is arranged vertically and movably at the position below the guide groove 13 corresponding to the connection buckle 10, the lower end of the buckle arm 8 is provided with a first guide slope 14 on the side close to the base 1, and the upper end of the plug 12 is provided with a second guide slope 15 on the side away from the base 1. When the plug 12 moves upward, it is inserted into the gap between the buckle arm 8 and the base 1 so that the buckle arm 8 is deformed outward. The socket and the five-hole panel 2 are assembled together by buckle connection. When disassembling, it is only necessary to push the plugs 12 on both sides upward and insert them into the gap between the corresponding buckle arm 8 and the base 1 so that the buckle arm 8 is deformed outward, so that the connection buckle 10 on the base 1 is separated from the buckle hole 9 on the buckle arm 8. At this time, the five-hole panel 2 can be pulled out upward. No external tools are required for disassembly, which is convenient and labor-saving, and is conducive to later maintenance operations.
